根据功能安全标准，不同的汽车安全完整性等级(ASIL)对应不同的硬件指标要求。通过对硬件指标和诊断覆盖率的分析，提出了可以满足功能安全硬件指标要求的转向系统控制器方案。该方案包括扭矩传感器、电机位置传感器、电机电流传感器、微控制器等部件，并对系统硬件指标的符合性进行了分析验证。

According to functional safety standards, different automotive safety integration levels (ASIL) correspond to different hardware metrics. Through the analysis of hardware metrics and diagnostic coverage, a steering system controller scheme that meets the requirements of functional safety hardware metrics is proposed. The program includes torque sensors, motor position sensors, motor current sensors, micro controllers，etc. The conformity of the system hardware metrics is analyzed and verified.
